340 mg (2.89 mmol, 1 eq) de cyanure de zinc sont ajoutés à 500 mg (2.89 mmol, 1 eq) de 6- bromo-pyridin-2-ylamine dans 10 ml de diméthylformamide dans un tube de micro-ondes. 170 mg (0.147 mmol, 0.05 eq) de tetrakis(triphenylphosphine)palladium sont ajoutés. Le milieu est chauffé à 170°C pendant 1 heure 30 au four micro-onde. 50 ml d'acétate d'éthyle sont rajoutés au milieu qui est filtré sur célite. Le filtrat est lavé à l'eau et extrait avec de l'acétate d'éthyle. Les phases organiques sont rassemblées et sont séchées sur sulfate de sodium. Le résidu est trituré dans de l'heptane. 6-Amino-pyridine-2-carbonitrile est obtenu sous la forme d'un solide orangé.  340 mg (2.89 mmol, 1 eq) of zinc cyanide are added to 500 mg (2.89 mmol, 1 eq) of 6-bromo-pyridin-2-ylamine in 10 ml of dimethylformamide in a microwave tube. 170 mg (0.147 mmol, 0.05 eq) of tetrakis (triphenylphosphine) palladium are added. The medium is heated at 170 ° C. for 1 hour in the microwave oven. 50 ml of ethyl acetate are added to the medium which is filtered on celite. The filtrate is washed with water and extracted with ethyl acetate. The organic phases are combined and are dried over sodium sulfate. The residue is triturated in heptane. 6-Amino-pyridine-2-carbonitrile is obtained in the form of an orange solid.

EXAMPLE 26 Biological Tests The compounds according to the invention exhibit inhibitory properties of AR type receptors. This AR receptor inhibitory activity is measured in a transactivation assay by dissociation constants KdR (rest), KdA (active) and Kdapp (apparent) according to the method disclosed in J. Molecular Biology (1965), 12 (1). ), 88-118, Monod J. et al. By inhibitor of ARs-type receptors is meant according to the invention any compound which has a dissociation constant Kdapp of less than or equal to 1 μΜ, and a KdR / KdA ratio <10, in a transactivation test.
Les composés préférés de la présente invention présentent une constante de dissociation inférieure ou égale à 500 nM, et avantageusement inférieur ou égal à 100 nM.  The preferred compounds of the present invention have a dissociation constant less than or equal to 500 nM, and advantageously less than or equal to 100 nM.
Le test de transactivation est réalisé dans la lignée cellulaire PALM (PC3 Androgene receptor Luciferase MMTV) qui est un transfectant stable contenant les plasmides PMMTV- neo-Luc (gène reporter) et pSG5puro-AR. The transactivation test is carried out in the PALM (PC3 Androgen receptor Luciferase MMTV) cell line, which is a stable transfectant containing the plasmids PMMTV-neo-Luc (reporter gene) and pSG5puro-AR.
Dans cette étude, l'affinité de chaque produit pour les 2 états des récepteurs (KdR et KdA) est déterminée ainsi qu'un Kd apparent (KdApp). Cette constante est une résultante des 2 Kd mais dépend également de l'équilibre initial du récepteur entre l'état actif et l'état repos (L0) et de son taux d'expression. Sa détermination se fait par la formule suivante: In this study, the affinity of each product for the two receptor states (KdR and KdA) is determined as well as an apparent Kd (KdApp). This constant is a resultant of the 2 Kd but also depends on the initial balance of the receiver between the active state and the rest state (L 0 ) and its expression rate. His determination is made by the following formula:
1/KdApp=(L0/(1 +L0))x(1/KdR) +(1/(1 +L0))x(1/KdA) 1 / KdApp = (L0 / (1 + L0)) x (1 / KdR) + (1 / (1 + L0)) x (1 / KdA)
Pour déterminer ces constantes, des « courbes croisées » du produit à tester contre un agoniste de référence, le methyltrienolone, sont réalisées en plaque 96 puits. Le produit à tester est utilisé à 10 concentrations et l'agoniste de référence à 7 concentrations.  To determine these constants, "crossed curves" of the product to be tested against a reference agonist, methyltrienolone, are carried out in a 96-well plate. The test product is used at 10 concentrations and the reference agonist at 7 concentrations.
A titre illustratif, un Kdapp de 40 nM est obtenu pour le composé (1 ), un Kdapp de 2nM est obtenu pour le composé (2), un Kdapp de 8 nM est obtenu pour le composé (19), un Kdapp de 1000 nM est obtenu pour le composé (18), un Kdapp de 200 nM est obtenu pour le composé (4). By way of illustration, a Kdapp of 40 nM is obtained for the compound (1), a Kdapp of 2 nM is obtained for the compound (2), an Kdapp of 8 nM is obtained for the compound (19), a Kdapp of 1000 nM is obtained for the compound (18), a Kdapp of 200 nM is obtained for the compound (4).
